Halosulfuron-methyl, pure product is a white powdery solid, mainly used for the prevention and control of broad-leaved weeds and sedges in wheat, corn, rice, sugar cane, lawns, etc., such as Cang Er, Mantulu, Ambrosia, Amaranthus, Wild Watermelon seedlings, Polygonum, Purslane, Solanum, Cassia, Morning Glory, Cyperus rotundus, etc. The agent can inhibit the biosynthesis of the branched-chain amino acids leucine, isoleucine, and valine in plants, but improper use may cause phytotoxicity to crops, and different crops or different varieties of the same crop have resistance There are differences in the resistance of herbicides. Halosulfuron-methyl is a sulfonylurea herbicide developed by Nissan Chemical Company and Monsanto Company. Its target is acetolactate synthase. my country’s corn planting area is large and there are many varieties. Studies have shown that it can effectively control the vicious weeds such as Cyperus rotundus, Abutilon, Commelina vulgare and Commelina communis in corn fields, and is safer to corn than Nicosulfuron and has broad application prospects.
The agent can inhibit the biosynthesis of the branched-chain amino acids leucine, isoleucine, and valine in plants, thereby inhibiting the growth of plant roots. The bioassay results of inhibition of the main root length of plants such as corn, potted plants, and rice are basically trending. Consistent. When the roots of plants are inhibited by Halosulfuron-methyl, the phytotoxicity symptoms are also the most obvious; on the contrary, the varieties with less inhibited root length grow vigorously, and there is no obvious phytotoxicity symptoms afterwards, and the inhibition rate of plant height is very low. The branched chain amino acids leucine, isoleucine, and valine have different synthesis capabilities, that is, different drug resistance. Therefore, Halosulfuron-methyl uses this feature to kill weeds. If the amount of this product is appropriate, it is suitable for wheat, corn, rice, Sugarcane has basically no effect or little effect, but it can greatly inhibit the biosynthesis of branched chain amino acids leucine, isoleucine, and valine in weeds.
Usage and dosage:
Halosulfuron-methyl is mainly used to control broadleaf weeds and sedge weeds, such as Cang’er, Mantulu, ragweed, Amaranthus retroflexus, wild watermelon seedlings, Polygonum, Purslane, Solanum, Cassia, Morning glory , Cyperus rotundus, etc. The method of use is both pre-emergence and post-emergence. It can be sprayed and sprayed on the plants. The pre-emergence application dosage is: 70-90 grams of active ingredients/ha; post-emergence: 18-35 grams of active ingredients/ha.
